It will be obvious that the cover plate 8 fully prevents outward leaka e of lubricant from the chamber 3. The on y other chance for leakage is through the opening-of the shaft 17. Such leakage, however, is positively prevented by a packing gland, comprisingpackingmaterial 26, held tightly in place around such shaft by a bushing 27 threaded into the partition and having a conical recess in its inner end adapted to 'hold the packing material wedged tightly against the shaft in a manner preventing the passage of lubricant thereby.

It IS believed that the construction and operation of my invention will be clear without further description. As lubricant flows.

- through" the meter, the member 11 will be rotated and-a definite amount of lubricant carried-frompne port to the other between the vanes 16, which are held accurately in contact with the wall-5 by means 'of the eccentricallyarranged block 15.- The rotation of the member 11 is transmitted through the reduction gearing 18-21 to the indicator 23,"which registers the amount of lubricant by moving over the dial 24. Obviously,

the body 1 of the meter is made as a sing casting and the making of the chamber 3 and its cooperating fparts circular provides for very easy manu acture. 'The invention therefore provides a very much improved meter bothfrom the standpoint of cheap ness of manufacture and simplicity of construction and operation.

Having thus described my invention, what I a plurality of radial slots, vanes'mountedone in each slot for radial sliding therein;

said vanes having each a. projecting rounded corner bearing on said shoulder a shaft supporting said rotary member, there being a bearing recess formed in one side wall of the chamber and a bearing opening formed through the opposite wall in which bearing recess and opening said shaft is rotatably mounted, the outer portion of said opening being widened into-a packing recess with the side wall thereof screw threaded and a bushing therein threadedly engaging the threaded portion of the recess for compressing packing material around the shaft, a

gear on said shaft adjacent said bushing,- an indicator, and reduction gearing connccting the shaft with said indicator.
